Does anyone know what data is Facebook trying to archive? Old user posts? But that doesn't fit this usecase because of the high latency.

Or maybe its just a nice content delivery mechanism to the NSA. Just ship a bunch of blue-rays instead of pesky optical fiber interception.

FB is required by law to store all its credit card transactions that every singal FB ads account has for 6 years. (So are other US based companies that process credit cards)

Surely, credit-card info can't span 100s of terabytes, even if they record each and every transaction.
